If obfuscation is all you need, you can Base64 encode the byte array
form of the guid, it'll end up around 24 characters or so:
---8<---
using System;
class App
{
static void Main()
{
Guid guid = Guid.NewGuid();
string encoded = Convert.ToBase64String(
guid.ToByteArray());
Console.WriteLine(encoded);
Console.WriteLine(encoded.Length);
}
}
--->8---
Do the reverse to get it back.
